Back in 1992, id Software released Wolfenstein 3D, a title that ushered in an entirely new genre and showed developers and gamers just how immersive and visceral a video game could be. Two decades later comes Rage.

For nearly 20 years the company has been improving the formula, creating more powerful technology, constantly redefining the genre it defined in the first place. In this first behind-the-scenes video for id's latest, Rage, John Carmack and friends talk about how they've instilled this new intellectual property with all they've built and learned since the Wolfenstein days to create what could be "the best thing that id's ever done."
